v1.388  April 11, 2020
    Desktop UI improvements:
        Added "tuning lock" to right-click popup menu. When active a single-click in waterfall
        or DX label area will briefly show a "tuning locked" overlay. Should perhaps be extended
        to include clicks in tuning scale. Does not effect other methods of tuning, e.g. entry in
        frequency box, click on +/- step buttons.

    Mobile UI improvements:
        Double-tap/touch brings up popup menu (same menu as right-click on desktop).
        Has tuning lock function same as desktop.
        Two finger pinch-in/out gesture will zoom the waterfall in/out. Tested on iOS & Android.

v1.389  April 12, 2020
    Added to popup menu: "edit last selected DX label". This means you can now edit DX labels
    on mobile devices.

v1.387  April 10, 2020
    Admin page control tab:
        By special request, added ability to limit number of simultaneous non-Kiwi API connections
            (e.g. kiwirecorder). This works in the same way (and overrides) the TDoA extension
            setting that limits the number of simultaneous TDoA connections.
    DX label edit:
        Passband frequencies can be entered using "k" and "M" suffixes for kHz and MHz.
        I.e. "2100" and "2.1k" are equivalent, as are "1200000", "1200k" and "1.2M".
        However subsequent display of the passband field is always in Hz.
        So after entering "-2.1k, 1.2M" on the next edit the field will display "-2100, 1200000" (Hz).

Paul, VK3KHZ, from PK's Loop Antennas, brought to my attention the http://plonsk.proxy.kiwisdr.com:8073 Kiwi that has these very wide masked band segments (AKA notched, blacklisted).

How was this done? It turns out it's a feature/bug of the existing masked frequency option available with dx labels. Normally when you setup a dx label and set the "type" menu item to "masked" the width of the masked frequency area is the passband of the label's mode (AM, CW, ...) But the dx label panel also contains a "passband" field where you can specify a custom passband which overrides the default.

Well, it turns out you can specify a ridiculously wide passband too. The audio code will clamp an overly wide passband to 12 or 20.25 kHz depending on the Kiwi FPGA configuration, but the masked frequency code will happily take your crazy passband width and block a huge segment of spectrum. So creating a dx label at 1120 kHz with the passband field set to "1180000" (the passband field is always in Hz) would mask the entire NA 530 - 1710 kHz AM BCB (530 = 1120 - 1180/2, 1710 = 1120 + 1180/2). The passband field also accepts a "lo, high" specification (e.g. "300, 2700" for a USB passband). So you could specify an large asymmetrical masked segment as well (label at 6 MHz, passband "-1000000, 2000000" to get a masked segment from 5 - 8 Mhz).

Pretty cool. Thanks Paul!

HTTPS on the Kiwi is not happening. Too many implementation/performance problems. We had the barroom-brawl about this years ago. Nothing has changed. Except that I'm less inclined than ever to work on stuff I don't perceive as important/interesting.

Maybe someone else will do this and deliver a 100% tested, validated patch. But history says otherwise.
